Here is an alternative to think about. It has a conventional corner location for the washroom, easy for guests to get to, but operators must stop the trains on the mains to lift out the bridge. And we lose the generous and lovely curves near the bridges, two spurs, and the viewblock that has been discussed. Trade-offs.
I extended the staging track into the access area to make swapping cars easier, but getting to the access area is not that easy anyway, so not sure if this is an improvement.
No change on the switch lead fouling the inside main yet.
